Application filed January 27 1906. Serial No. 140,696. (lIo model.) I

T0 at whom it mag concern:

Be it known that I, LOUIS C. HAMEL, residing at Stevens Point, in the county of Portage and State of Wisconsin, have invented certain useful Improvements in Windmills; and I do hereby declare that the following is a full,

clear, and exact description of the invention,- such as will enable others skilled in the art to which it appertains to make and use the same, reference being had 'to the accompanying drawings, which form a part of this specifica tion.

This invention relates to new and useful improvements in windmills.

The primary object of my invention is to provide a durable and effective mechanism for holding the sections composing the windwheel in the wind and to provide simple means for swinging said sections out of operative position.

The secondary object is to provide means for automatically lubricating the wearing parts, so that oil may be automatically carried from bearing to bearing, so that all parts requiringoil shall be kept lubricated, and to provide a construction whereby complication, and consequently friction and excessive wear, of the working parts is prevented. x My invention relates more particularly to that class of windmills known as the vaneless mills, in which an open wheel is used.

Inthe accompanying drawings I have shown in Figure 1 a front elevation, with portions broken away, ofa windmill embodying my invention. Fig. 2 shows a sectional view with portions removed. Fig. 3 shows an enlarged detached detail disclosing the arrangements of the automatic oiler. tional view,with portions removed, of the main driving-shaft and the connected members. Fig. 5 discloses a front view of the governorwheel, showing the coacting lugs of the windwheel and governor-wheel, also the spring as used in my'd'evice. Fig. 6 discloses a front View showing one of the friction-plates and connected pawl-wheel. Fig.7 shows abroken enlarged detail disclosing the arrangement of the friction-disks andthe connected shoe.

In the accompanying drawings I have shown in Figs. 1 and 2 the upper portions of a number of uprights or standards 1, as usually employed in windmill construction,which stand- .Fig. 4; shows a sec-.

ards are provided with the cap A, to which by means of suitable bolts aare secured the standards 1. This head A is provided interiorly with a conical seating 3, as shown in Fig. 1, with the the upper outer circular collar 2, as disclosed in Fig. 2. Below the uprights or standards 1 are provided with a snitable step-casting B (shown in Fig. 1) and secured by the bolts a. This step-casting B is provided with a circular opening 5 and upon one side with a projecting ear 4, (also shown in Fig. 2,) and held within this car 4 by means of the burs 7 is a guide-rod 6. Held within the opening 5 of the step-casting B and revolubly working within the upper collar 2 of the cap Afis the pivot-collar E of the casting, with the two downwardly-extending bars 13, which below are secured to a disk 1), (shown in Fig. 1,) from which extends a boss I), the disk and boss being perforated to form a lower bearing. This hub bearing works snugly within the opening of thestepcasting B. Slidably held within this lower hub-bearing b and within a removable bushing 0 is the upper end of the pumpplunger A, which above by means of the pin 0 is secured to the pitman C, as shown in Figs. 1 and 2, and this =pitman extends through the pivot-casting E and is secured to the pin 0, extending from the disk 20, forming part of the wind-wheel shaftH, as shown. This pitman C is hollow and above is provided with an extending nipple 37, so that anything ontering the nipple 37 will gravitate to the bearing containing the pin 0 within the upper end of the pitman C, and from this upper bearing the oil will gravitate down the hollow pitman to the lower bearing, receiving the pin 0 within the lower end of the pitman, and from thence the oil will flow laterally outward and drip down the pump-plunger A to lubricate the bushed hearing within the hub b, insuring free operation of this.

same may be grasped below and secured by any suitable means to draw the same downward to pull down the bracket 8. Extending upward from this loosely held collar 11 is a rod f, which by means of the ear 6 is secured to said collar 11, this car forming a portion of said collar, as shown in Fig. 2. The rodf passes through a suitable opening within the hub b, adjacent to the bushing c, as shown in Figs. 1 and 2.

Extending from the upper end of the pivotcasting E is an arm F, provided with an upwardly-extending web 14, and this arm F and web 14 form suitable bearings, upon which is held a tube 17, which is secured to said web and arm by means of the' U-bolts 15 and 16, as clearly shown in Fig. 2. This tube 17 is interiorly provided, as is clearly shown in Fig. 4, at one end with the bearing 18 and at the other end with the bearing 19, so that between these bearings 18 and 19 is formed the chamber provided with suitable absorbing material, such as cotton-Waste or lampwick, as is shown at 25 in the drawings. At a suitable point, as indicated by the arrow .2, this tubing is perforated, so that the lubricating-oil may be fed into this tubular chamber, forming an oil-reservoir.

Surrounding the tube 17 at the end adjacent the bearing 18 is a collar 23, which is in the form of a drip-cup, as shown in Figs. 4 and 3, and extending upward from this dripcup 23, as shown in Fig. 2, is the arm 26, perforated to provide a bearing for the rockshaft 27. This rock-shaft is provided with the crank-arm 28 and is surrounded by the spring 29, so that this rock-shaft is normally held in one position under spring tension in such a manner as to hold the bracket 8 (shown in Fig. 1) in its uppermost position by means of the connected rodf.

The dripcup 23 is provided with a laterally-extending tube 24, (shown in Fig. 3,) filled with a suitable wick 25, and the end of this tube 24 is so positioned that in operating the nipple 37 comes in contact with the wick 25, so that what oil has collected at the end of this tube 24 is directed into this nipple intermittently as the nipple is successively brought in front of this tube 24.

Ileld within the bearings 18 and 19 is the main wind-wheel shaft H, which at one end is provided with the crank-disk 20, as shown in Fig. 4, and at the remaining end has secured to it the hub 45, from which extends the hub-arms 56, as shown in Fig. 4.

Surrounding the tube 17 at the end adjacent to the bearing 19 is a yoke 36, (shown in front view in Fig. 7,) andthis yoke above supports the rock-shaft 27, as shown. Below this yoke 36 supports a pin 35, to which are secured the two counterpart brake-shoes and 34. From the upper end of the brake-shoe 33 extends a link 31, while extending from the brake-shoe 34 is a link 32, and these links are secured to the opposite ends of the bar sauce 30, secured to the rock-shaft 27, as shown in Figs. 4 and 7. As this rock-shaft 27 is rocked the shoes 33 and 34 are carried toward or away from one another. By virtue of the spring 29 these brake-shoes are normally held outward their fullest capacity.

The hub 45 is provided with a semicircular lug 45, (shown in Fig. 5,) and this lug 45 is normally resting against a lug L, forming part of the governor-wheel 44, provided with the spokes 43. An ordinary coil-spring M is secured to the lug L and at its remaining end is secured to the head 45, so that the lug 45 of the friction-head is normally against the lug L of the governor-wheel 44. This governor-wheel 44 is provided with a bevel edge 42, (shown in Fig. 4,) and this edge 42 extends at an angle, as shown, and adjacent this governor-wheel 44 and loosely working upon the wind-wheel shaft II is a ratchetprovided frictioudisk 40, a face view of the same being shown in Fig. 6. This frictiondisk 40 is also provided with an angular flange 42, (shown in Fig. 4,) so that the two flanges of the friction-disk 40 and governorwheel 44 present a V-shaped peripheral surface, and each brake-shoe 33 and 34 is also provided with a V-shaped seating, so that when these brake-shoes are brought together they bind upon the disk 40 and governorwheel 44.

Secured to the wind-wheel shaft II and held between the governor-wheel 44 and the friction-disk 40 is a holder I, provided at each end with a seating 41, adapted at each end to receive a pawl 42, forced outward into engagement with the ratchet-teeth of the friction-disk 40 by means of the springs h, as shown in Fig. 6.

Secured to the hub-arms 56 are a plurality of fork-ended arms 60, (shown in Fig. 1,) which are secured by the U-bolts ct, and within the bifurcated ends 59 of these arms 60 are held the cross-bars 63, holding the blades K, each holder being provided with an outwardly-projecting ear 62. The blades K arefurthersecured by means of the holder 64, as shown in Fig. 1.

In Fig. 1 it will be noticed that I have shown six such bifurcated arms 60. Secured to each set of cross-bars 63 and G4 are held a set of blades K. Projecting from each car 62 is a rod 63', secured to one of the spokes 43 of the governor-wheel 44, as shown in Fig. 1. The holders 63 are secured by means of suitable rods 61, as disclosed.

Extending from the upper end of the pivotcasting E is an outwardly-extending weightarm 50, to which is secured a suitable counterweight to counterpoise the Weight of the wind-wheel. Extending upward from this weightarin 50 is a truss-bar 52, over which extends a truss-rod 57, secured to the outer end of the arm F, as shown in Fig. 2, this truss-rod passing above over the bolt 56. Below, passing through the truss-bar 52, is a the hub and the governor-wheel, it will be remembered, are in spring contact by virtue of the interposed spring M. Now should the wind velocity increase sufiiciently to throw the sails outward it would result in the shipper-rods 63 drawing backward against the tension of the spring M ofthe governor-Wheel 45, so that the lugs L and 45 would travel away from one another. As the wind velocity increased the governor-wheel 45 would travel backward more and more. So, also, as the wind velocity decreased the'governorwheel would travel forward again, permitting the sails to come more and more into their normal position, in which they lie practically in one plane. By this means I provide a governing mechanism so constructed that the wind-wheel will practically revolve at the same speed irrespective of the force or the velocity of the wind. Now should it be desired to cut the wheel out of the wind the operator would actuate the rock-shaft 27 to apply the brake-shoes 33 and 34. This would result in stopping the movement of the governor-wheel, though the wind-wheel itself is revolving, which results in all of the shipperrods being actuated to tilt the sails outward. The Wind-wheel, however, will have continued to rotate the shaft H and the connected pawls 42, working over the ratchet within the friction-disk 40, so that after'being thrown out of the wind thesails cannot tilt back, being held by virtue of the pawls 42 in engagement with the friction-disk 40, clutchedby means of the brake'shoes 33 and 34. This sudden throw-out of the wind-wheel will not carry with it a shock or strain upon the working effects, for the reason that if the driving power of the wind-wheel is greater than the frictional contact between the friction-disk 40 and the shoes 33 and 34 this disk 40 and the bevel edge 42 will revolve within their shoes 33 and 34 until the momentum of'the wind-wheel is lost.

Having thus described my said invention,"
